[QUOTE="HPLouis, post: 16216101, member: 5445"] I went to the dyno in June of last year. Here's the thread: [URL]https://www.svtperformance.com/threads/not-happy-at-dyno.1161444/[/URL] Another thread with my issues: [URL]https://www.svtperformance.com/threads/maxed-out-with-2-76-pulley.1161560/[/URL] Dyno graph: [ATTACH=full]1496612[/ATTACH] Datalog: [ATTACH=full]1496613[/ATTACH] Mods at the time: Billetflow 2.76 pulley NGK TR-6 plugs MRT Catted H-Pipe Borla ATAK catback Varrstoen ES7 rims with 265/35/18's in the front and 315/30/18's in the rear Mail order tune from JDM (they were the original tuner) I have the Pro Racer Package and looked over tune. Car still has stock MAF transfer function. It still has the stock airbox and paper filter. Fuel pump DC was 92 and injectors maxed out at 100. Car only made 406 rwhp. Now I’m frustrated. The car only made 406 rwhp but tons of torque! Why? The timing was at 18 and I know I had the stock air box, filter and silencer but still, it should have made more. The A/F was decent too. It should have made more power. [/QUOTE]
